    As places go through significant changes, so do their inhabitants. Experts refer to this as urban evolution, where genetic transformations occur to help make these environments more adaptable. 

    An example is the rat population in New York City. Studies have shown that Big Apple rodents have evolved to have shorter rows of teeth, likely due to their diet of softer foods in an urban setting.

    Annual minimum 1984: 6,3M sq km; 2012 3,39M sq km; 2025: 4,28M sq km. 2012 has been the historical minimum, due to a strong storm in August that melted the most recent ice, and a streak of warmer temperatures.

    Urban coyotes also went through a similar evolution, according to a January 2025 study published in Genome Biology and Evolution. Research has shown that urban coyotes have become more adaptable to starches due to increased access to pet and human food.

    The removal of the houses -a block called "Spina di Borgo"- and the new wide road were a major project designed during the Fas*ist era, to celebrate the agreements between the Church and the Italian state, that put end to a 6-decade long quarrel between the Kingdom and the Papacy (and regrettably still stand, providing public money, tax exemptions and plenty of influence to the Church). Due to the war it was completed only two decades later.

    Before the invention of light bulbs and electricity, people relied on flames as their primary light source. The less illumination there was, the darker night skies became, unlike in today’s perpetually illuminated world. 

    Author and environmental philosopher Christoper Preston blames light pollution for less starry skies and disrupted circadian rhythms.  

    “There is no doubt (urbanization) is a path causing an unstoppable shift in who we, as well as the species that like to live alongside us, essentially are,” Preston wrote in an article for The MIT Press Reader.

    I wish they'd left all the decorative foo-fa-rahs on the tops of the buildings and the gate. And kept the balconies on the left. Even added more! I do like the pavement though.

    My niece was at the Sorbonne for a year. I told her never to go to Marseille. The school sent her group there on a field trip. She was mugged immediately. Couldn't they have sent them to Provence or Normandy? I have read this city has been the crime capital of europe for 2 centuries!
